2.6.3 Example for Applying the Smart Link Functions

Networking Requirements
As shown in
backbone network through uplink devices Switch A and Switch B in dual-homed mode.
Switch A and Switch C are connected to uplink devices in dual-homed mode. One out of each
link pair needs to be blocked to prevent loops. When the active link fails, the data flows can be
rapidly switched to the standby link to ensure normal services.
In addition, a monitoring mechanism is required to prevent service interruption caused by faults
of the uplink. This monitoring mechanism enables the downlink to quickly detect the fault of
the uplink. When the uplink fails, link switching can be performed immediately to shorten the
duration of service interruption.
